[PATCH v3 2/2] mei: bus-fixup: change pxp mode only if message was sent
From: Alexander Usyskin
Date: Wed Nov 16 2022 - 07:48:17 EST
Move PXP mode state machine to SETUP mode only if
memory ready message sent successfully to the firmware.
Leave it in INIT mode otherwise to allow try to send message later.
